In today’s edition of “Engineering Roundtable,” SparkFun Engineer Chris Taylor guides you through the use of a microcontroller to perform audio spectrum analysis. He explains the basics of working with the audio spectrum and ultimately links up his project with a propane torch. Why? Well…why not? Check it out:
Feel free to leave any comments or questions in the comments section below and we’ll do our best to answer them! Thanks for watching and we’ll see you again soon with another edition of “Engineering Roundtable!”

(puns are fun) This is a google map showing the current supercharging stations. From this alone, you should be able to get to any destination within 100 Miles of any of these locations and do so without any range anxiety. If your final destination has charging options then you can be comfortable within 200 miles of any of these locations. If you look into public charging stations you can probably cross the country in any direction. By 2015 the Tesla stations should enable cross-country trips with ease. I am going to get to know California then the country.
If you are listening Tesla – Phoenix next; I have travel plans and a place to stay all ready to execute.
A mini fact: So far the average charge time for the car has been about 2 hours for a normal day to work and back. If I drive more conservatively someday perhaps that time will come down (unlikely anytime soon). In the photo, the surface that looks like a button is indeed one. When you push this the little flap, that is part of the running lights, pops open. Push the plug into the car and the green ring will light up. Pulsing slowly or quickly depending upon the current battery level. Press the button again to pull out the plug. All of that will only work if you have the key fob with you. I tried to remove the plug when the key fob was in the house and it would not unlock/come out. Also, the car can detect the plug is in and will not let you drive off. Good thing for those (not yet fully) caffeinated early morning departures. I am not keen to look at the PG&E bill but will do so shortly to see how we are doing in that regard.
On a slightly different note today all driving about has been electric. A gas-free day today. I’ll maybe start tracking the car and bike usage (all cars and bikes). When the cars are used to do anything that counts and if the bikes are used to do anything useful other than exercise that will count. In a gas-free world, I’d take my electric bike to work while the rest of the day’s outings would be in the Tesla. A fully electric day. Half and half would be we use 1 gas and one electric. Full gas would be we used no electric. There will be the odd day we don’t go any place at all. I should probably track this on a Google sheet.
Lastly will be doing the daily cash costs of gas vs electric from the simple fueling only perspective. I am certain if I use all the gas items from the CC bills over the last year and the electric bills there should be some way to see how much money shifted to electric and if there are any savings at this level. That’s data collection so someday soon again.
The Tesla Model S is a thrill to drive. I love speed and acceleration so it is a good fit. To say it has all the features of an electric car sells it short. It has all the features of any car you’d ever really want. It just happens to be electric. A few posts will be here over time about the car and when there are interesting developments but otherwise expect the hardware and geekery that’s considered normal.
Today I drive the car to work for the first time. My impression of the car, dark in the garage, fully charged, was one of latent power. For an odd reason, I perceive it as asleep and not off. Odd that I perceived anything of this nature in fact.
